ANDREW F. CURTIN, OF MEDFORD, MASSACHUSETTS.

BALL-COCK.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed April 23, 1915. Serial No. 23,328.

To all whom t may concern:

Be it known that I, ANDREW F. CURTIN, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain new.and useful Improvements in Ball- Cocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in ball-cocks, and more partielllarly, to an improvement in ball-cocks provided with a water passage surrounding the valve and connecting the inlet and the outlet of such formation that the flow of water therethrough is retarded. In the use of ball-cocks provided with water passages of this descriptiomif the pressure of the water lowing through them drops below a certain point, the tanks supplied by them are filled too slowly.

The object of the present invention is to 'produce a retarding water passage ball-cock having an auxiliary 4water passage or bypass connecting the inlet and the outlet and provided with a controlling valve by which the volume of water passing therethrough may be regulated.. To this end the invention consists in the improved ball-cock hereinafter described and particularly pointed out in the claims.

In the accompanying drawings illustrating the preferred form of the invention, the ball-cools comprises a valve-shell or body in which is received a longitudinally movable l valve 2 controlled by the float. The upward 1 float causes the valve to be pressure of the the valve-seat 3 formed on seated against lone end of a-removable member 4 held in position by an inlet tube 5 coupled to the lower end of the valve-body by a couplingnut 6. The flow of the water from the inlet 7 formed in the member 4 to the outlet A 8 is through a circuitous or spiral passage 9 which has a retarding effect upon the water; the retardation of the iow of the water being utilized to cause sudden closing of the valve thereby eliminating the hissing sound accompanying a slow closing of the valve. The ball-cock thus far described forms the subject-matter of Letters Patent No. 829,462 issued to me August 28, 1906. In addition to this circuitous spiral or retarding water passage 9 which constitutes the main water lend of the by-pass m higher pressures passage the improved ball-cock is provided with an auxiliary, free-flowing water passage or by-pass 10, located in the valveshell or body 1 and separated from the circuitous passage by the inner wall 11. One end of the by-pass gives into an inlet chamber 12 surrounding the valve-seat 3. This chamber receives the stream of water fromthe inlet before it passes into the circuitous passage 9; The, other end of the by-pass g1ves-1nto the outlet chamber 13 into which .the circuitous passage discharges and which l1n turn discharges through the outlet 8. r

screw valve 14 is received in the discharge and seats itself at 15 just below the discharge chamber 13. When the stream of water flowing through the passage 9 is under sufficient pressure to fill the tank within the desired period, the valve 14 is screwed down on its seat 15. Where, however, the water pressure falls below the required degree, the valve 14 is unscrewed to an extent sufficient to permit the necessary additional quantity of water to pass out through the outlet chamber 13 and the outlet 8 to fill the tank within the required time.

' Under normal conditions of use, that is to valve 2 is unseated, flows only through the circuitous or spiral passageway 9 on its passage from the inlet7 to the outlet 8. But under abnormal conditions, that is to say, in places where the'wat'er pressure falls below normal, the valve 14 .is unscrewed until thel volume of water flowing through the opening thereby made between the passage 10 and the outlet chamber 13 is large enoughA together with the water flowing through the" circuitous passage-way 9 to fill the tank within the required time.

The present invention contemplates a ball-cock provided with a main .retarding water passage from the inlet to the outlet andan auxiliary water passage or by-pass from the inlet to the outlet, this latter passage being closed during normal water pressure conditions of Operation of the ballcock. The auxiliary passage is provided with means by which, when conditions make it necessary to use the passage, the volume of water flowing through the passage from the inlet to the outlet may be properly regulated. It is to be observed that' with the auxiliary passage is closed, but With the lower pressure it is opened more or less.' The invention may, therefore, be embodied in other forms than that described above.

Having thus described my invention, What I claim is:

1. A ball-cock having in combination, a

valve-body having an inlet and an outlet, a main retarding flow passage connecting the inlet and the outlet, a valve-seat located in the inlet, a valve movable longitudinally in the valve-body and adapted to press against the valve-seat for controlling the flow of water through the inlet, and an auxiliary or free-'How by-pass passage connecting the inlet and the outlet having provision permitting a portion of the Water passing through the inlet to flow through the bypass.

2. A ball-cockl va Ive-body having main retarding flow inlet and the outlet, valve-body through the passage and an auxiliary or free-How by-pass passage connecting the inhaving in combination, a an inlet and an outlet, a passage connecting the a. valve-movable in the for controlling the How of Water4 let and the outletl havingva valve for regulating the How of Water through the by-pass operating when opened Wider with decreased Water pressure to shorten the valve operating time. 3. A ball-cock having in combination, a valve-bodyhaving an inlet and an outlet, a main retarding flow passage connecting the inlet and the outlet, an auxiliary or free-flow 'by-pass passage connecting theinlet and the outlet, and means for regulating the proportionate amounts of Water flowing through the retarding and the free flowing passages.
